Find z such that 5% of the standard normal curve lies to the left of z.
These questions involving z are the worst. Any help appreciated
Solution :
Using standard normal table ,
P(Z < z) = 5%
P(Z < z) = 0.05
See the probability 0.05 in the z table the corresponding z value is -1.645 .
P(Z < -1.645) = 0.05
z = -1.645
